Hi ​@sumisha, here's how to enable Business Domain Analysis:

1. Open up the Profiling step, and click the button in the top right corner to switch to Advanced configuration.  
2. In the tree on the left-hand side, expand the Inputs node, navigate to your input and then to the column of interest.
3. In the middle panel, mark the checkbox for Analyse Business Domain.

   

    

The Business Domains that the tool can identify are prebuilt into the code so there's no additional configuration, just switch it on and run the profiling plan.

I hope this helps!
